Filter by:RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells of by stopping them from dividing. Pemetrexed disodium may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase I trial is studying the side effects and best dose of giving pemetrexed disodium and docetaxel together in treating patients with advanced solid tumors.
The purpose of this study is to assess the safety and activity of ARN-509 in men with advanced castration resistant prostate cancer. Patients will first be enrolled into Phase 1 of the study to identify a tolerable dose for the Phase 2 portion of the study. In the Phase 2, 3 different cohorts of patients will be enrolled to evaluate the safety and activity of ARN-509.
Rationale: Dose escalation in external-beam irradiation has proven to benefit outcome in local prostate cancer. Randomized trials were performed up to doses of 78 Gy in 2 Gy fractions. Nevertheless, the five-year biochemical relapse rate still was approximately 35% in the high-dose arm. Therefore further dose escalation seems to be required. A feasibility study up to appr. 85 Gy on the entire prostate has already been performed and showed acceptable toxicity when combined with adequate position verification. Higher doses to the entire prostate are expected to increase severe toxicity. As local recurrences only occur at the site of the primary macroscopic tumour area the next step in increasing the dose should be an ablative boost to the macroscopic tumour alone, while electively irradiating the rest of the prostate to the current gold standard dose. Feasibility of this approach has been shown for an ablative dose of 95 Gy to the macroscopic tumour within the prostate.
Two memory research findings (the spacing and testing effects) can dramatically improve retention of learning, but they have largely have been ignored by educators. The researchers have developed a novel form of online education (termed 'spaced education') based on these two effects which has been shown in randomized trials to improve knowledge acquisition and boost learning retention. Using prostate cancer screening as an experimental system, the researchers investigated whether spaced education could durably improve clinicians' behaviors, not just their knowledge.
This is a prospective study in which patients with castrate-resistant prostate cancer and bone metastases will undergo imaging, donate blood, bone marrow and urine samples, and where possible primary tumour and bone metastatic tissue, before and during treatment with ZD4054, an orally active specific endothelin-A antagonist. The samples will be used primarily for biomarker studies, and it is hypothesized that these will inform on the mechanism of action of this drug. Magnetic Resonance Imaging (MRI) will be performed to evaluate emerging functional imaging endpoints as markers of early response in bone metastatic prostate cancer.
This study is being done to test the safety of a single high-dose of radiation therapy before radical prostatectomy (removal of the prostate). The investigators want to find out what effects, good and/or bad, the radiation will have on men undergoing prostatectomy. The investigators are especially interested in men who are at risk for having cancer cells that have spread outside the prostate.
The main purpose of the study is to investigate the safety and tolerability of AZD3514 when given orally to patients with castration-resistant prostate cancer (CRPC)
The purpose of this study is to assess the effectiveness of dioxin on prohibiting prostate cancer progression as measured by PSADT (prostate-specific antigen doubling time).
The purpose of this study is to compare how subjects feel after receiving injections of two different types of GnRH six months apart. One injection is given under the skin of the abdomen, and the other one into the muscle of the buttock or thigh.
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This clinical trial is studying blood samples in predicting how patients with prostate cancer will respond to treatment with docetaxel.
